title: Target hazard quotient evaluation of cadmium and lead in fish from Caspian Sea.
abstract: Heavy metals are being increasingly released into the natural waters from geological and anthropogenic sources. The distributions of several heavy metals such as cadmium (Cd) and lead (Pb) were investigated in muscle and liver of three different fish species seasonally collected from Caspian Sea (autumn 2011-summer 2012). The concentrations of all metals were lower in flesh than those recorded in liver due to their physiological roles. The target hazard quotient (THQ) index for fish was calculated. Estimation of THQ calculations for the contaminated fish consumption was calculated to evaluate the effect of pollution on health. Total metal THQ values of Pb and Cd for adults were 0.05 and 0.04 in Anzali and Noshahr, respectively, and for children were 0.08 and 0.05 in Anzali and Noshahr, respectively.
